How long the decomposition of compostable plates takes is a question that many people might ask, and several factors influence what the answer is. Generally, if a compostable plate is placed in a commercial compost facility, it will take less than 180 days to completely decompose.
The amount of time this will take will fluctuate depending on factors like temperature, moisture, and pile composition. When itâs hot and the pile is moist and has a good ratio of carbon to nitrogen (20:1-100:1 in this case), a three month decomposition is possible.But outside of those parameters, it may take up to a year. Also, a family of five will produce much more compost material than a single person living alone.he single personâs pile will take longer simply because it needs to build up a critical mass. Either way, the bottom, or oldest part of the pile, will be ready first. Worm Bin: 1-3 Months. With worm bin composting, the more well-established the worms are in numbers the quicker they are able to process food scraps.
